Simulation Of Echo Cancellation Of Speech Signal In Noisy Environment
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 10
Abstract
Acoustic echo cancellation is important for audio teleconferencing when simultaneous communication of speech is necessary. In acoustic echo cancellation, a measured microphone signal contains two signals such as the near-end speech signal and the far-end echoed speech signal. The goal is to remove the far-end echoed speech signal from the microphone signal so that only the near-end speech signal is transmitted. In speech signal processing slow convergence and high computational burden are the main problems. The proposed m e t h o d is based on using adaptive filter and uses the least mean square (LMS) algorithm to control a filter coefficients to reduce the echo in the input speech. Here the algorithm is developed and simulated with help of LabVIEW.
